In my first playthrough, I noticed that all the dead bodies (I’m not certain it’s actually 100%) strewn throughout Black Mesa are whole and intact. I think there should be numerous instances where dead bodies should have missing limbs or being torn in half, either across the waist or head-to-crotch or diagonally. I did notice coming across appendages on their own, a leg here, an arm over there which one would expect to find, considering the circumstances.
Also, whenever I came across a Zombie or a Bullsquid in the process of feeding, the human body was always intact. It could be a situation where the feeding process had just begun, but there should also be instances where it may have begun some time earlier. In that case, the body should be partially consumed and not whole. How about Xenians feeding on HECU marines? Maybe not, to avoid sympathetic feelings towards the HECU? Screw the sympathy factor. They should be on the menu as well. What better way to fill your belly than devouring someone who just killed your fellow Xenian buddy?
Also, are there any instances of unconscious humans having an active headcrab on its head, other than shortly after the resonance cascade event? A headcrab on an unconscious female would be appropriate as well. These types of scenarios should be found throughout Black Mesa. How about on a HECU marine? Sympathy reasons, again? Mmmmm.
Now, I’m not a macabre person, just thinking of ways to deepen the immersion factor on a monumental and tragic event.
Maybe some of these observances/suggestions can be incorporated into future patches/possible further game development.
